Letters Patent No. 85,104, dated December 22, 1868.

mews-n GAS-MACHINE.

The Schedule referred toin these Letters Patent and making part of the same.

To all whom it may concern Be it known that we, P. H. LAWLER and WILLIAM H. GIBSON, of Rochester, in the county of Monroe, and State of New York, have invented anew and useful Gas-Machine; and we do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the' accompanying drawings, making part of this specification, in, which- Figure 1 is a vertical longitudinal section.

Figure 2 is a vertical transverse section.

' The nature of our invention willibe understood from the drawings and specifications.

To enable others skilled in the art to make and use our invention, we will describe its construction and operation.

On the inside of a metal case, A, made in any of the "knownforms of air-carburetting machines, We form a chamber, 0, fig. 1', by putting in a partition, a, which is sufficiently high to be above the top of the fluid that may be put in to carburet the air. a,

At the bottom of the partition there is a small hole,

y, fig. 2, to allow the. fluid'to flow from the main part of the machine 'to the chamber 0, formed by the partition a, so that it will at all times find its level on both sides of the partition.

Inside of this machine we suspend a lever, c. To one end we attach a float, B, that rests on the fluid, and is thereby regulated vertically as the fluid rises and falls. On theother end of the lever owe pivot a valve, 11, which covers the exit-port of the pipe E, leading from the supply-chamber F.

Inside of this machine we suspend an agitator, that is keptiir motion byaveights or springs. This agitator is formed by placing on the'ends" of a shaft, h, disks J, which are connected together by several tubes, II, which extend through the disks J. 7 Us On one end of the agitator we form a chamber, K, by an extradisk, p, and joining it to the disk on the shaft at their peripheries. hole, :0 in the centre, sufiiciently large to allow the shafi h topass through, and also the air-supply pipe P, which extends from the outside of the shell forming the machine into the chamber K, and bending upwards near to the point Where the spiral tubes enter this chamber.

The disk 1) has a circular i The object of this invention is to make an air-car' I diminishes, and regulates the flow from the supply-.--

chamber, this being necessary, as any over-supply'of the fluid causes awaste, and an irregular supply causes a defective light. The air passes into the chamber K from the outside, through the pipe P, and as the agitator is revolved, it passes through the spiral pipes ]E[ into the fluid, thoroughly mixing with it, and then passing ofi' into the 'gasometer A, on top of the ma chine.-

If the machine is partially filled with water and carburetting-fluid, it is necessary to have small holes, at,-

at the level of the carburetting-fluid, so that it will be on a level on each side of the partition.

By suspending the regulating-float in the fluid, in a chamber separate from the one in which the agitator works, it is not afi'ected by undulation of the fluid, as it would be if in the same chambenand therefore operates the valiTewith a steady motiony as it risesor falls with the fluid. w What we claim as our invention, and desire tosecure by Letters Patent, is-

l. The compartment 0, in combination-with the float B, lever c, valve 11, and supply-pipe E, as and for thepurpose herein. shown and described.

- 2. The air-supply pipe I, chamber K, and spiral pipe H, all acting ooujointly, as and for the purpose shown and described.
